20T/H RDF Pellet Plant In Brazil

Construction content and scale

The RDF pellet plant in Brazil project covers an area of 4,325m2 and a construction area of 5,575m2. The main building is a 5-story factory building A (this project only rents the 1st and 2nd floors, of which the 1st floor is a crushing and molding production workshop, the 2nd floor is an office, canteen and dormitory, and a 1-story factory building B (mainly a raw material warehouse and a finished product warehouse).

The main engineering components of this project are shown in the table below.

Product plan

The product situation of this RDF pellet plant in Brazil project is shown in the table below:

Note:

RDF is the abbreviation of Refuse Derived Fuel. It has the characteristics of high calorific value, stable combustion, easy transportation, easy storage, low secondary pollution and low dioxin emission. It is widely used in drying engineering, cement manufacturing, heating engineering and power generation engineering.

SRF is the abbreviation of Solid Recover Fuel. SRF is usually refined RDF. SRF is not garbage, but a clean, homogeneous, high-quality and high-calorific value fuel. It can be used in power plants or cement plants to replace traditional fossil fuels such as coal. Moreover, SRF is a very environmentally friendly fuel. Its carbon dioxide emissions are only one-fourth of coal, and NOx emissions are also significantly reduced.

Equipment status of Brazil RDF pellet production line

The main equipment of this RDF pellet plant in Brazil project is as follows.

Water supply and drainage

The water supply of this RDF pellet plant in Brazil project is supplied by the local municipal tap water network. The water used in this project is mainly domestic water and ground washing water, of which the domestic water consumption of employees is 760m3/a and the ground washing water is 145.8m3/a.

The factory adopts the rain and sewage diversion system. Rainwater is collected by the factory rainwater pipe network and discharged from the factory rainwater pipe.

The daily office sewage of the project is treated by the three-level septic tank and the oil and slag separation tank, and the ground washing wastewater is treated in the sedimentation tank and then discharged to the sewage treatment plant through the municipal sewage pipe network.

Process design of Brazil SRF and RDF pellet processing project

The moisture content of the raw materials collected in this RDF pellet plant in Brazil project is less than 30%, and the finished material is about 20% after adding calcium oxide, so there is no need to set up a drying process.

1. Loading:
   The materials are transported to the primary crusher through the coarse crushing feed chain plate conveyor; each material has a certain shape and size (non-powder), a certain density and weight.
2. Primary crushing:
   The primary crusher only breaks down large objects into particles with a size of less than 50mm during the crushing process.
3. Iron removal (magnetic separation):
   The metal blocks (chips) are automatically adsorbed or unloaded by the automatic iron remover, and the metal blocks (chips) are almost dust-free. In the magnetic separation, the material is in a closed conveyor belt, and there is almost no additional disturbance of the material. The amount of dust is very small and can be analyzed quantitatively.
4. Secondary crushing:
   The secondary crusher only breaks objects into particles with a size of less than 30mm during the crushing process.
5. Mixing:
   Calcium oxide is placed in the material bin of the molding machine, and it is fully mixed with the crushed raw materials and then transported to the molding machine via the conveyor belt to enter the next process.
   Among them, calcium oxide mainly plays a drying role. The raw materials collected by the project are pressed and molded after adding calcium oxide and drying. No humidification and drying are required during the production process.
6. Compression molding:
   The mixed raw materials are transported to the molding machine for molding. Electric energy is used in the production process of the project. The molding process uses electric heating. The finished products produced by the RDF pellet machine are transported to the belt conveyor for bagging.
   The molding process is physical extrusion molding. The surface molding temperature of the material is about 150℃ and the internal temperature is 40~50℃. Since the decomposition temperature of raw materials such as waste plastics is above 270℃, no organic waste gas is generated during the molding process.
